This is a place-holder article while I build this website. Here is some inline_code, as well as a code block:

fn main() {
    println!("Hello world!");
}

I want to write some inline maths $\int_0^\infty e^{-x^2}$ and formulas $$\frac{Df}{Dt} = \frac{\partial f}{\partial t} + \boldsymbol v\cdot\nabla f$$
